Hello! I have a quick question. I am a permanant resident with a 10 year green card which will expire Feb 2025.I am wanting to visit Australia for a month this year(2024) around Aug-Sept,just wondering if green cards are like passports and you shouldnt travel with them with less than 6 months before they expire? If I travelled to Australia in Aug-Sept I would be renewing the green card as soon as I returned to the U.S.A. Thanks for any help!
